A few months ago, director Chelsea Taylor was watching a documentary about the anti-gay Westboro Baptist Church with friends and noticed that the organization incorporates pink triangles in some of its imagery. Her friends weren't aware that the Nazis had used pink triangles to identify homosexuals, just as they used yellow stars to identify Jews; she had learned that when she read Martin Sherman's play “Bent,” which follows a gay man sent to a concentration camp. Taylor is now directing the play for Proxy Theatre Company. (The cast includes, from left, Rodman Bolek and Richard Anthony.) It's the first Proxy offering since it began its residency at the Overtime Theater. The triangle factors in the play — after he and his lover are arrested, the man claims to be a straight Jew so that he won't be branded with the pink triangle — and in the set, which will have that shape. “The idea is that they are entrapped within a label,” Taylor said.
